Data Transfer Procedure

1. REQUEST EVALUATION

When a new cross-border transfer is proposed:

Step 1: Complete Transfer Request Form

  • Business justification
  • Alternative solutions considered
  • PII categories and volume
  • Destination country and entity
  • Processing purpose and duration

Step 2: Initial Risk Assessment

  • Is destination country adequate?
  • What PII is being transferred?
  • What is the sensitivity level?
  • Are there alternative approaches?

Decision Point:

  • Low risk → Proceed to Step 3
  • Medium/High risk → Conduct full TIA

2. TRANSFER IMPACT ASSESSMENT

For medium/high risk transfers:

  1. Assess destination country laws
  2. Evaluate government access risks
  3. Review data protection framework
  4. Identify required safeguards
  5. Document supplementary measures
  6. Calculate residual risk

Approval Required From:

  • Data Protection Officer
  • Legal Counsel
  • Information Security Officer
  • Business Owner

3. LEGAL MECHANISM SELECTION

Decision Tree:

Is destination country adequate?
├── Yes → Proceed with minimal documentation
└── No ↓
    Is transfer necessary for contract performance?
    ├── Yes → Use SCCs + TIA
    └── No ↓
        Can you obtain explicit consent?
        ├── Yes → Document consent + safeguards
        └── No ↓
            Is there another derogation?
            ├── Yes → Document derogation + justification
            └── No → Transfer not permitted

4. IMPLEMENTATION

Steps:

  1. Draft and execute appropriate agreement (SCCs, DPA)
  2. Implement technical safeguards
  3. Configure security controls
  4. Train staff on procedures
  5. Enable monitoring and logging
  6. Test data subject rights processes
  7. Document everything

5. ONGOING COMPLIANCE

Monthly:

  • Review transfer volumes
